(Cl. 68-5) This invention relates to improvements in an apparatus for continuously leading textiles into or out of a pressuretreating chamber in an apparatus for fluid-treating textiles in a pressure-treating chamber filled with a dyeing solution, bleaching solution, steam or any other treating fluid.

There already have been suggested apparatus of various structures for continuously leading textiles into or out of a pressure-treating chamber air-tightly or liquid tightly. But they have a defect that the structure is complicated or that perfect air-tightness or liquid tightness is not attainable. The present invention eliminates such defects.

An object of the present invention is to provide an apparatus, of a simple structure, wherein textiles can be continuously led into or out of a pressure-treating chamber substantially perfectly air-tightly or liquid tightly.

Another object of the present invention is to provide an apparatus wherein the operation is smooth and the maintenance cost is remarkably low.

The present invention relates to an apparatus for continuously leading textiles into or out of a pressure-treating chamber wherein a feeding roll device consisting of two component rolls each coated on the peripheral surface with an elastic material and pressed against each other, is set outside a textile inlet or outlet of a pressuretreating chamber, an annular pressure fluid chamber is formed around a textile passing port on the upper surface of said textile inlet or outlet, an annular peripheral surface sealing member is fitted in the opening on the upper surface and both side surfaces of said pressure fluid chamber and a cover having an annular pressure fluid chamber and an annular end surface sealing member fitted in the opening on the inside surface of said pressure fluid chamber is provided at each side of a hollow space formed between the parts of both component rolls of said feeding roll device opposed to each other and the upper surface of said textile inlet or outlet so that, when a pressure fluid having a pressure higher than the pressure in said pressure-treating chamber is introduced into both of said annular pressure fluid chambers, said annular peripheral surface sealing member may be pressed against the peripheral surfaces of both component rolls of said feeding roll device opposed to each other and said annular end surface sealing members may be pressed against both end surfaces of the component rolls of said feeding roll device.

FIG. 10 illustrates another embodiment.

An embodiment of the present invention shall now be explained with reference to FIGS. 1 to 4.

In the drawings, 1 is a feeding roll device consisting of two component rolls 2 and 2' pressed against each other. Said component rolls 2 and 2' of said feeding roll device are made by applying coatings 4 and 4' made of such soft elastic substance as elastic rubber to the peripheries of roll bodies 3 and 3' made, for example, of a metal, respectively. 5 is a textile inlet or outlet of a pressure-treating chamber 6. Two upper and lower textile passing ports 7 and 7' are made in said inlet or outlet 5. An annular oil storage chamber 8 is formed around the upper textile passing port 7. An oil feeding pipe 9 is connected to said oil storage chamber. An annular oil discharging chamber 10 is formed around said lower textile passing port 7. An oil discharging hole 11 is connected to said oil discharging chamber 10. 12 is an annular pressure fluid chamber provided around said annular oil storage chamber 8. Said pressure fluid chamber 12 is provided with a pressure fluid inlet hole 13. 14 is an annular peripheral sealing member made, for example, of elastic rubber of a U-shaped cross-section. Said sealing member 14 is fitted in the opening on the upper surface and both side surfaces of said annular pressure fluid chamber 12. 15 is a cover to seal each side of a hollow space G formed between the parts of the peripheral surfaces of the component rolls 2 and 2 and the upper surface of the textile inlet or outlet 5. An annular pressure fluid chamber 16 is formed on the inside surface of said cover 15. A pressure fluid inlet hole 17 is made also in said pressure fluid chamber 16. An annular end surface sealing member 18 made, for example, of elastic rubber of a U-shaped crosssection is fitted in the opening on the inside surface of said pressure fluid chamber. 19 and 19' are oil storage chambers provided above both sides of the textile inlet or outlet 5. Oil feeding pipes 20 and 20' and oil discharging pipes 21 and 21 are connected to said oil storage chambers 19 and 19, respectively.

In case the apparatus of this embodiment is to be used to lead in a textile, only the oil storage chamber 8 is filled with a lubricating oil 22 but no lubricating oil is put into the other oil storage chambers 19 and 19. On the other hand, in case said apparatus is to be used to lead out a textile, only the oil storage chambers 19 and 19' are filled with lubricating oil 23 and 23', respectively, but no lubricating oil is put into the other oil storage chamber 8.

24 in FIG. 5 is another example of the sealing member to be used in the apparatus of the present invention. This example is an integral combination of the peripheral surface sealing member 14 and end surface sealing members 18 illustrated in FIG. 4.

The operation of the above mentioned embodiment of the present invention shall now be explained.

In case the above mentioned embodiment illustrated in FIGS. 1 to 4 is to be used to lead in a textile, the textile a is held between the peripheral surfaces of the component rolls 2 and 2' of the feeding roll I pressed against each other and is inserted into the upper and lower textile passing ports 7 and 7' in the textile inlet 5, the oil storage chamber 8 is filled with the lubricating oil 22 and a fluid of a pressure higher than the pressure in the pressure-treating chamber 6 is pressed into the pressure fluid chamber 12 through its inlet 13 and into the other pressure fluid chambers 16 through the inlet 17. In such state, when the component rolls 2 and 2' of the feeding roll device 1 are rotated in the directions indicated by the arrows X and X, respectively, the textile a will move in the direction indicated by the arrow Y and will be led into the pressure-treating chamber 6. At this time, as the fluid of a pressure higher than the pressure in the pressure treating chamber 6 is introduced into the pressure fluid chamber 12 as mentioned above, the annular peripheral surface sealing member 14 will be pressed against the peripheral surfaces of both component rolls 2 and 2' of the feeding roll device 1 with the pressure higher than the fluid pressure in the high pressure-treating chamber 6. Further, at this time, as the fluid of a pressure higher than the pressure in the pressure-treating chamber 6 is introduced also into the other annular fluid pressure chambers 16, as mentioned above, the end surface sealing members 18 will also be pressed against both end surfaces of the component rolls 2 and 2 of the feeding roll device 1 with the pressure higher than the fluid pressure in the pressure treating chamber 6. Therefore, the pressure-treating fluid entering the space G between both component rolls through the textile passing ports 7 and 7' in the textile inlet 5 from the pressure-treating chamber 6 will never be likely to leak out between the peripheral surface sealing member 14 and the peripheral surfaces of both component rolls 2 and 2 and between the end surface sealing members 18 and the end surfaces of both component rolls 2 and 2. Further, as the textile a is held under a strong pressure between the elastic coatings 4 and 4 of both component rolls 2 and 2, respectively, of the feeding roll device 1, the pressure fluid in the pressure-treating chamber 6 will not leak out even between both surfaces of the textile a and the peripheral surfaces of both component rolls 2 and 2'. Therefore, the textile a can be led into the pressure-treating chamber 6 substantially perfectly air-tightly or liquid-tightly. Fur- 1 ther, in such case, the lubricating oil 22 in the oil storage chamber 8 will be fed between both sealing members 14 and 18 and the peripheral surfaces and both end surfaces of both component rolls 2 and 2 of the feeding roll device by the capillary tube phenomenon. Therefore, the leakage of the pressure-treating fluid in the pressuretreating chamber 6 through the textile inlet part can be more effectively prevented and the sliding between both sealing members 14 and 18 and both component rolls 2 and 2 can be made smooth. The excess of the lubricating oil 22 fed into the oil storage chamber 8 will overflow from the upper end edge of the upper textile passing port 7, will fall along the inner surface of said textile passing port 7, will enter the oil discharging chamber 19 without touching the textile a and will be discharged out through the oil discharging hole 11. Therefore, the lubricating oil is not likely to be deposited on the textile a to stain it.

In case the textile is to be led out of the pressure-treating chamber 6, lubricating oil 23 may only be put into the oil storage chambers 19 and 19' as mentioned above and both component rolls 2 and 2' of the feeding roll device 1 may be rotated in the directions opposite those indicated by the arrows X and X, respectively. The op eration and effect in such case are exactly the same as in the above mentioned case of leading in the textile and therefore shall not be explained here.

Another embodiment of the present invention shall be explained with reference to FIGS. 6 to 10. In the drawings, 1 is a feeding roll device consisting of two component rolls 2 and 2' pressed against each other. Both component rolls 2 and 2 of said feeding roll device are made by applying coatings 4 and 4' made of such soft elastic substance as elastic rubber to the peripheries of roll bodies 3 and 3 made, for example, of a metal, respectively. 5 is a textile inlet of a pressuretreating chamber 6. An annular pressure fluid chamber 12 is formed on the upper surface and both side surfaces of said textile inlet 5. Said pressure fluid chamber is provided with a pressure fluid inlet hole 13. 14 is an annular peripheral surface pressing member made, for example, of elastic rubber of a U-shaped cross-section. Said pressing member is fitted in said annular pressure fluid chamber 12. 25 and 25' are laminated sealing members each made of such material low in wear and friction as, for

example, a fluorine resin or a fluorine resin containing a filler. Said sealing members are fixed to the upper surface of the textile inlet 5 with a plurality of bolts 26 so as to cover said peripheral surface pressing member 14. 15 and 15 are covers to seal each side surfaces of a hol.ow space G formed between the parts of the peripheral surfaces of the respective component rolls 2 and 2' of the feeding roll device 1 and the upper surface of the textile inlet 5. Annular pressure fluid chambers 16 and 16 are formed on the inside surfaces of said covers 15 and 15', respectively. Said pressure fluid chambers 16 and 16' are also provided with pressure fluid inlet holes 17 and 17', respectively. Annular end surface sealing members 18 and 18 made, for example, of elastic rubber of a U-shaped cross-section are fitted in the openings of the inside surfaces of said covers 15 and 15', respectively. 27 and .27 are annular sealing members each made of such material low in wear and friction as, for example, a fluorine resin or a fluorine resin containing a filler. Said scaling members are fitted to the inside surfaces of the respective end surface sealing members 18 and 18'.

FIG. 9 is a vertically sectioned view of a textile outlet part. The structure of this part is the same as of the textile inlet part illustrated in FIGS. 6, 7 and 8 except that the positions of bolts 26 are different.

The operation of the embodiment illustrated in FIGS. 6 to 9 shall be explained in the following. In case this embodiment is to be used to lead in a textile, the textile a is held between the peripheral surfaces of both component rolls 2 and 2 of the feeding roll device 1 pressed against each other and is inserted into the pressuretreating chamber 6. A fluid of a pressure higher than the fluid pressure in the pressure-treating chamber 6 is pressed into the pressure fluid chambers 16 and 16 through their inlet holes 17 and 17, respectively, and into the other pressure fluid chamber 12 through its inlet hole 13. In this state, when both component rolls 2 and 2' of the feeding roll device 1 are rotated in the directions indicated by the arrows X and X, respectively, the textile a wil move in the direction indicated by the arrow Y and will be led into the pressure-treating chamber 6. At this time, as the fluid of a pressure higher than the pressure in the pressure-treating chamber 6 is introduced into the pressure fluid chamber 12 as mentioned above, the annular peripheral surface pressing member 14 will be uniformly pressed against the peripheral surfaces of both component rolls 2 and 2' of the feeding roll device 1 through the sealing members 25 and 25', respectively, with the pressure higher than the fluid pressure in the pressuretreating chamber 6. Further, in such case, as the fluid of the pressure higher than the pressure in the pressure-treating chamber 6 is introduced also into the other pressure fluid chambers 16 and 16', as mentioned above, the end surface pressing members 18 and 18' will also be uniformly pressed against both end surfaces of the component rolls 2 and 2' of the feeding roll device 1 through the sealing members 27 and 27, respectively, with the pressure higher than the fluid pressure in the pressuretreating chamber 6. Therefore, the pressure fluid entering the space G between both component rolls 2 and 2 from the pressure-treating chamber 6 will never be likely to leak out between the sealing members 25 and 25 and the peripheral surfaces of both component rolls 2 and 2 and between the sealing members 27 and 27' and the end surfaces of both component rolls 2 and 2'. Further, as the textile a is held under a strong pressure between the elastic coatings 4 and 4' of both component rolls 2 and 2' of the feeding roll device 1, the pressure fluid will not leak out between both surfaces of the textile a and the peripheral surfaces of both component rolls 2 and 2. Therefore, the textile a can be led into the pressure treating chamber 6 substantially perfectly air-tightly or liquid-tightly. Further, as the sealing members 25, 25' and 27, 27' are all made of such material low in wear and friction as, for example, a fluorine resin or a fluorine resin containing a filler, the apparatus can be operated smoothly and the surfaces of the feeding rolls will not be hurt. In case the sealing members have been worn by extensive use only the sealing members can be easily replaced. Therefore, the maintenance cost of the entire apparatus can be remarkably reduced. The present invention has various advantages.

Now, in case the textile is to be led out of the pressure treating chamber 6, the positions of the bolts 26 to fix the sealing members 25" and 25 may be made different from the case of FIG. 6 as shown in FIG. 9 and the component rolls 2 and 2' of the feeding roll device 1 may be rotated in the directions indicated by the arrows Z and Z, respectively. The operation and effect in such case are exactly the same as in the above mentioned case of leading in the textile and therefore shall not be explained here.

Further, in the case of FIGS. 6 to 9, it is possible to form an annular oil storage chamber and oil discharging chamber above both sides of the textile inlet or outlet as shown in FIGS. 1 to 3. This state is illustrated in FIG. 10 as an example of the inlet. The operation and effect of the oil storage chamber are the same as in FIGS. 1 to 3. In the case of the outlet, the positions of the bolts 26 to fix the sealing members 25 and 25 will be on the opposite sides.

Not only the apparatus specifically explained above but also any apparatus embodying the spirit of the present invention are included in the purview of the present invention.
